Single Use Logistic Glider

Abstract

A disposable airdropped glider. The glider body is constructed from precut panels cut from (MDO) or (HDO) plywood and assembled with pocket-screw joinery or piano hinges. A skid board forms a landing surface and a cargo deck roll-off surface. The glider has pivoting wings and struts. The glider has a triple-tail, a flat nose and honeycomb paperboard panels between the nose and the cargo. Wings are pivoted from a position overlying the fuselage to a flying position by gas springs in wing spars which are compressed by a chain attached to the fuselage through a rotating bracket such that the gas springs are compressed when the wings are folded. The airfoils are plastic extrusions with openings that hold the wing spars and co-formed jury spars which attach the upper and lower surface of the wing. A parachute uses a part of the tail structure to form a deployment drogue.

CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority on U.S. Provisional Application No. 62 / 400,527 filed Sep. 27, 2016, which is incorporated by reference herein.STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0002]This invention was made with government support under contract number D16PC0011 awarded by DARPA. The government has certain rights in the invention.BACKGROUND OF THE INVENTION[0003]The present invention relates to the resupply or delivery of payload by airdrop or gliders.[0004]In tactical combat defending a hardened position, or engaging the enemy behind their lines has considerable tactical advantage. In the defense of a hardened position the defenders are considerably less exposed to fire than the attackers and thus can withstand a superior enemy. Further, if the enemy cannot reduce such a hard position and bypasses the position, it leaves an active fighting force in its rear, which either ties dow...

AI Technical Summary

Benefits of technology

[0006]The air resupply device of this invention is a disposable glider of low cost which can be dropped from an aircraft and glide to a landing point up to 130 statue miles from the drop point, depending on the altitude at which the airplane is dropped. The glider body is constructed from precut panels cut from medium density overlay (MDO) plywood which resists water, weather, wear and degradation. High density overlay (HDO) plywood with a more rugged, smoother surface can also be used. The plywood panels are joined with one inch self-tapping pocket hole screws which form a high-strengt
